What is it? This large magnetic rock is known by geologists as an inselberg, meaning literally “Island Mountain”, basically this is an isolated remnant left after the slow erosion of the original ancient mountain range
Where is it? It is located in the UNESCO-listed Uluru-Kata Tjuta National Park World Heritage Site 350 km southwest of Alice Springs. - It is said by some to be located on a major planetary grid point much like the Great Pyramid in Egypt (did I just hear the theme tune of the ‘Twilight Zone?’)
Size: Uluru is the second-largest monolith in the world after its little known ‘Big Brother’ Mount Augustus, which is also in Australia and is over twice the size of Uluru. Ulur, however, is no minnow, it is more than 318 m (986 ft) high and 8 km (5 miles) around. It also extends 2.5 km (1.5 miles) into the ground. It was described by explorer Ernest Giles in 1872 as "the remarkable pebble".'
Colours: It is notable for appearing to change colour as the different light strikes it at different times of the day and year, changing appearance from a rich pink at dawn to orange at noon to a particularly remarkable sight; when it briefly glows to radiant ocher at sunset. Although rainfall is very uncommon in this semiarid area, during wet periods the rock acquires a silvery-grey colour, with streaks of black algae forming on the areas that serve as channels for water flow.
